I had a power surge about a week ago tv start cutting on and off days later a box pop up stated no channels registered instructed my to hold the ok button on remote for 3 seconds I did it started reprogramming the tv and will ask u questions about the tv be sure to follow the instructions u should be go to go.????
Is it attached to the aerial/cable socket.?
If it is, then the main control board has probably failed.?
Changing it out is a fiddly but achievable job, but it's probably only worth it if you can pickup a used replacement part from eBay or similar.?
Otherwise a brand new replacement board may be up to $150.?
Testimonial: "I have replaced the main and power board. does the same thing. A message flashes quickly saying, hold remote ok button for 3 seconds and then shuts down. The word sanyo lights up then it cuts off!"
Have you tried turning it on & operating it using the manual control buttons.?
It's always possible that there's an issue with the remote control sensor.?
IF
it works with the manual controls, then it will be either the remote or the remote-control sensor that's problematic.?

Hi,
As the TV can run the automatic scan ,the problem is with the cable.The signal is not comnin to the TV to store the channels.Try setting the antena properly/call your cable TV operator and inform them about this problem and you can get rid of this problem.
Thanx

Main system control memory IC fault. This is a very small IC; have 8 solder terminals, and can be located very near to the main system control-chroma IC. Check and replace it. Be sure to replace it with the same number printed on it; in all respect. Otherwise, it won't go. http://electronicshelponline.blogspot.com/ Before replacing it, try a reset to this set, and then check.
There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here.
